§ Mr. Chidgey
To ask the Chancellor of the Exchequer what assessment he has made of the potential economic benefits deriving from environmental improvements of(a) City diesel and (b) oxygenated fuel; and what consideration he has given to the introduction of fiscal incentives to encourage their use. 
§ Mr. Oppenheim
We keep the potential economic and environmental benefits of City diesel and oxygenated fuel under review. The Government do consider, where appropriate, the use of fiscal incentives to promote practices which are environmentally and economically beneficial, but each case is looked at on its merits.
